Java.net.socketexception: socket closed error is usually caused by not setting the connection timeout

Solution:

This problem can be solved by the following methods

If use keepalive is checked in the basic of HTTP request sampler, it is recommended to use the Advanced tab:

1. Implementation is httpclient4

2. Connect in timeouts sets a value of 10-60 seconds, which indicates the idle timeout of the connection, so as to avoid the disconnection of the connection caused by the keep alive header that does not receive the response from the tested end
